Application filed February 24,;1908. Serial No. 417,437.

Be it known that I, PAUL G. LEIs'rNER, a

citizen of the,United States, and resident of St. Charles, Missouri,

have invented certain new and useful Im rovemnts in Grease- Cups, of which .the 'ollowing is a specification containing a full, cle'ar,-an'd exact dereference being had to theacconi- .panying drawings, forming a part hereof.-

yinvention relates to a grease cup, and the Object of my invent-ion is to construct a grease cup especially designed for automo- I bi1es, although" it may be used on various devices wherever lubrication is required.

7 To the above "purposes, my invention consists in certain novel features of construction and arrangement of parts which will be "hereinafter more fully set forth, pointed out ling drawings: 1 indicates an angular v .provlded on in the claims, and illustrated in the accompanying drawings, in which: Figure l is a side elevation of my invent-ion'; Fig 2 is a central vertical section; and Fig. 3 is'a'transverse section taken on. the line 33 of Fig. 2.

Referrin'g'b'y numerals to the'accompanystem, its lower end with a series of screw threads'2, by means of which it may be attached to the parts of the automobile or other devices which are desired to be lubricated. Formed integral with the stem member 3 and the stem ing 5, for

1 is the bottom member of the cup 3,uvhich is substantially saucer-shaped and the peripheral-edge of which is provided with a series of screw threads 4:. Formed in the 1 is a central openthepassage of the grease from the cup. -6 indicates a the stem a1. a v Y .-7ind-ic'ates the removable member,

or cap, of the cup, which is internally screw threaded, as designated by S, and adapted to b i screwedpnto andremoved-from the'member 3. Theexteri'or of said cap 7 has aprojecting millededge 8, by which it may be manipulated; l'The' cap 7 is a series of vertical parallel parallel grooves ,9, between pressions or whichare proi grojvi'ded withe 1 I flange formed integral with cant of clamping device is forced against the shoulder 6;

j ec tingpafllel and. vertical ribs or beads 10, the function of referred to.

which .will be hereinafter 11 indicates a substantially U-shaped clamping device to preve'nt'the cap 7 from being accidently unscrewed or displaced fromthe member 3, by the. vibration and jar to which the grease cup is subjected while in use. Said clamping device is provided with a portion 11 in which is formedan angular aperture, through which the angular; stem 1 may -be forced, or in construction the and to' 'assistlin holding the clamping device in place I employa washer 12, which .is also-forced onto the stem 1 and against the clampin The said clamping device is provi ed with elastic arms 13, which arms are substantially parallel and are adapted to are projections onto thisstem and' device.

clamp'or grip the cap 7 at points'diame'trically opposite to 79 v upper ends and l4, thesaid projections being rounded and adapted to fit into the grooves 9. Inconstruction,' the' clamping device is stamped out of spring brass-material, and the arms 13 bent as shown. The projections ld are also stamped from the "material composing the RI'IDS-y The clamping action of the arms 13 is sufiicient to prevent thecap 7 from working unscrewed by -vibration of the device to which the cup enough to prevent the. cup from being screwed up or down on the member 3 by hand.

The cup is intended to be used for a lubria plastic or semi-plastic distinguished from a liquid state.

Havin fully what I c laim is;

A grease cup, comprising a tubular stem,

a portion of the exterior of which is noncircular; a saucer-shaped member integral with the top of the stem, the edge of which member is screwthreaded, an interiorly is applied, but it is not great I state, as

screw-threaded cap adapted to 'be screw bein a continuous series of vertically dispose grooves formed in the outer face of the cap, a plate fitted onto the non-circular. pertionof the tubular stem, a retaining washer located on said stem and hearing against the plate, a pair of oppositely arranged spring arms integral with the plate and extending upward on opposite sides of the cap; and projections formed on the ends I of the in the grooves of the cap.

In testimony whereof, I have signed my name to this specification, in presence of two subscribing Witnesses.
